SPINNING AND TWISTING MACHINE SPECIFICATION formingpart of Letters Patent No.643,302, dated February 1a, 1900. Application filed July 6, 1899. Serial No. 722,977. (No model.)

To all whom it may concern:

Be it known that I, WILHELM N EUBAUER, technical director of the Elsassiche Gesellschaft, residing at Bischweiler, Alsace, in the Empire of Germany, have invented a new and useful Jute Spinning and Twisting Machine, of which the following is a specification.

This invention relates to an improved spinning and twisting machine which differs in principle from the known machines of this kind and has in consequence many advantages.

In the known machines the fliers are so connected that they are also put in rotation by the driving of the spindles.

In the improved machine only the fliers are put in action and revolve about stationary spindles. is that any single flier of the machine can be put in or out of action independently from the others at any time without trouble, and the spinning of the yarn and the exchanging of a spool at any time when such spool is full is easily operated,'so that the mechanism for simultaneous exchanging of the whole of the spools of the machine can be dispensed with.

A further advantage of the improved machine is the especially quiet working of the same, as the fliers revolve upon a suitable bearing and are safely guided by a tubular piece fitting upon the spindle, so that the disadvantageous vibration of the spindles occurring in the known machines is entirely avoided, and consequently repeated dressing of the same, often accompanied by a necessary and expensive renewal of the bearings, is

also not here required. Formerly, also, when removing the spools, the fliers, being generally,

screwed on the spindles, had to be loosened by a wooden hammer, which often resulted in the breaking of a flier-arm or screw-shank of the same. In the improved machine, in consequence of the loose mounting of the fliers on the spindles, this disadvantage is suppressed. Moreover, the construction of the machine does not necessitate the use of straps, spindles, bands, or cords, and consequently no attendance is required for such parts. The fliers can be readily caused to rotate in the reverse direction independently The principal advantage derived of the driving devices of the spinning-machine, so that the spinning-frame can also be used for twisting.

In the annexed drawings, Figure 1 is a vertical section of a part of the machine, showing the improvements. Fig. 2 is asection on line w of Fig. 1. Fig. 3 is a view from the right of Fig. 1. Fig. 4 is a plan view of a flier.

The construction of the machine is as follows: The flier or is similar to the hithertoused fliers, with the difference that on the flier-shoulder a disk 0 is fixed, provided with two holes 0 as near as possible to the flierarm and the shoulder. (See Fig. 4.) From each of those holes a slit reaches to the edge of the disk for the purpose of introducing the yarn. Further,the flier is lengthened downward by a tubular stem f, Fig. 1, which fits closely onto the stationary spindle and which is so long that in the lowest posithree centimeters into the wooden spool, so that in this manner the revolution of the spool effected by the winding of the thread is supported by the flier. bearing-point on its upper end. The upper exterior diameter of the spindle fits into the inner diameter of the flier-stem so far as the latter extends. From this point downward the spindle has an exterior diameter the same as that of the flier-stem f or the same as the diameter of the bore of the wooden spool. The spindle is journaled vertically in the two bearings Z Z, of which Z is arranged in the usual breast-beam and l in the usual stepbeam. The spindle is lifted by the weight Q by means of the lever H until the disk (I of the flier comes against a friction-plate Z composed of papier-mach, leather, or the like.

The driving of the fliers is effected by the shaft w, which is driven directly from the driving source by means of pulleys. On this shaft are iron disks g g 9 arranged exactly the same distance apart as the spindles, between which, in round guides'of the crosspiece T, are the rods 7510 movable forward is journaled a friction-disk Z movable upward and downward by means of an arm '0. This friction-disk is also pressed against the respective plate g by the weight G rocking The spindle s has a and backward. On each of these rods there tion of the spool-frame it still reaches two or r the rod by means of lever h. The weightlevers H and h are joined together by means of a rod m, so that each weight G and Q can be moved downward independently one from the other; but if by means of the pedal F, fixed on the spindle underneath the stepbeam, the spindle is pushed down then the flier also goes down, the disk 0 is disengaged from the friction-plate Z and the flier stops. Also at that moment the upper lever-arm h is lifted by the rod 1%, and thereby the friction-plate Z is removed from the iron disk g. At the same time also the catch 19, pivoted on the step-beam, drops down by its own weight onto the pedal F and holds the spindle and friction-plate in their out-of-gear position until the catch is again set free by the operator. This rest position is shown in Fig. 3. If the flier is to be again in action, the catch 19 is set free, whereby first the friction-plate Z is pressed against the iron driving-disk g by action of the weight G, and the spindle s is immediately lifted by the weight G till the flierplate 0 touches the friction-plate P. If the shaft to is in action, then the disk g, the friction-plate Z and the flier-plate C are put in action.

In order to cut or exchange the spool, the flier is first stopped by the pedal and then the friction-plate Z pushed backward by the lever D. In order that the friction-disk when in action cannot move away from the driving-disk g, the washer t of the rod 70 is provided with a nose which has a hollow corresponding and engaging with a guide qof the beam T when the flier is out of action. During working the nose pushes against the guide, so that the friction-disk cannot move laterally.

The proportional load of the weights G and Q is easily ascertained by first calculating the pressure of the friction-disk upon the driving-disk g, taking into consideration the leverage, and then taking Q of such load that, besides effecting the same pressure upward, it also lifts the weight of the spindle and the flier and surmounts the friction in the two bearings Z Z.

In order to effect the operation of twisting with the spindles, the shaft w, with the disks g,is moved a few millimeters toward the leftthat is to say, so much that now the left side of the right driving-disk is exactly the same distance from the axis of the spindle as the right side of the left disk was from the same spindle. Then only the lever h with the weight G and the connection-rod mare moved from the right to the left.

Having now particularly described and ascertained the nature of this invention and in What manner the same is to be performed, I declare that what I claim is- 1. In a spinning and twisting machine, a non-rotary vertically-movable spindle with means for keeping it pressed normally upward and carrying the spool, the flier mounted thereon and having a depending tubular stem entering and serving as a guide for the spool, a friction-disk carried by the flier, a second friction-disk in driving contact with said first-named disk and means for driving said second disk, substantially as described.

2. In a spinning and twisting machine, a non-rotary vertically-movable spindle with means for keeping it pressed normally upward and carrying the spool, the flier mount ed thereon and having a depending tubular stem entering and serving as a guide for the spool, a friction-disk carried by the flier and having two oppositely-arranged holes with slots leading thereto for the entrance of the yarn, a second friction-disk in driving contact with said first-named disk and means for driving said second disk, substantially as described.

In witness whereof I have signed this specification in the presence of two witnesses.

WILHELM NEUBAUER.
